To all whom it may concern:

Be it known that T, dorm FRANoIs Snna, a citizen of the United States,residing at Tampa, in the county of llillsboro and State of Florida,have invented certain new and useful Improvements in Signaling Apparatusfor Submarine Boats; and l[ do hereby declare the following to be alull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The present invention relates to signaling apparatus for ships, moreespecially to vessels of the sub-marine type, and proposes aconstruction whereby such vessels may be e nipped with means forsignaling when a oat or submerged; and wherein the apparatus isserviceable to assist in rescuing the vessel in the event 0t itsbecoming disabled when submerged.

The invention proposes the mounting at a mast on a biioyant support orraft which is carried by, and as a fixed part of, the submarine boat,said mast being equipped with a yard arm designed to carry the transmitting and receiving wires of a wireless system; and also applicable toserve in place of the mast now used in connection with the visible codesystem for signaling when the ship is on the surface. The connectionsbetween the raft and the vessel are such that when the boat is submergedthe raft may, from within the boat, be readily released to allow theraft had to the accompanying drawings, in

which like reference characters designate the same parts in the severalviews, and in which- Figure 1 is a central vertical sectional view ofthe apparatus and a portion of the sub-marine vessel. Fig.2is asideelevation,

partly broken away, of the raft and mast. Fig. 3 is a top plan view ofthe structure shown in Fig. 1. Fig. 4 is a top plan view out the deck ofthe vessel as equipped for carrying the raft. Fig. 5 discloses'thegearing for releasin the raft from the vessel. Fig. 6 is a detailsectional view of the releasable connection em lo ed, and Fig. l is atop plan view, part y in section, of the part shown in Fig. [1". 1

Referring to the several views in further detail and with like referencecharacters indicating corresponding parts in the difierent figures, 1designates the upper deck or bulk-head of a sub-marine boat whichcarries, throu h the medium of a series of cradles 2, a no ant supportor raft on which is mounts the signaling apparatus. This apparatusconsistent a mast l and a yard arm 1" constructed of tubular aluminum orsteel, and to said arm l wires 1 and other parts are connected forwireless signaling. This equipment (1 and 1) is also serviceable inconnecting, with its usual signaling service of marine vessels, and itis further adapted for the installation of telephone and telegraphservice.

The raft comprises a pair of air tight tanks 3 to which is secured adeck consisting ot a middle plank l, side planks 5, connecting crossplanks 6, and a pair of longitudinally extending beams 7 that aresecured to the under sides of said cross planks *(see Figs. 1 and Ateither end the buoying tanks 3 are provided with metal bands or strips 8connected with the deck and having each an end terminating in a claw 9through the medium of which the raft is detachably connected with thesubmarine vessel. There may be for each vessel more than one of theserafts and the accompanying equipment it necessary.

The means for connecting the raft with the vessel and for efiecting therelease of the former consists of tour bracketsll) (2 being shown)having web portions 11 which seat against and are secured to the underside of the deck 1 through the medium at bolts 12. The openings in thedeck for these connections are made water-tight by suitable packings 13.J ournaled within the web 11- and an arm l4c on each of the brackets isa shaft 15 having'its upper end provided with a half nut 16 adapted topass through a similar shaped opening 17 in the claw 9, and when turnedto engage said claws and secure the raft to the vessel.- On their innerends the shafts 15 are provided with beveled pinions 18 meshing withsimilar pinions 19 mounted on a pair of shafts 20, which shafts 20 areadapted to be turned for releasing the raft through the medium of amanually operated gearing comprising a shaft 22, cone gears 2324 and ahand turning wheel 25.

The signaling apparatus carried by the raft is adapted to have signalcontrolling connection with the vessel through the medium of a suitablyinsulated conductor cable 26 that extends through the mast 1, and has ajoint or coupling 27 where it passes through the deck 1[ A hawser 28also connects the raft with the boat and is intended to be used fortowing purposes.-

The cable 26 and hawser 28 are ordinarily stowed within a housing on thedeck 1, which consists of a casing or chest 29 which has a removablecover 30, said cover being normally held closed through the medium ofthe deck beams 7 seating thereon, as shown in Fig. 1. The chest 29 isprovided with a transverse partition 30 forming a chamber within whichis swivelly mounted a sheave 31 provided with a hawser pulley 32 andadapted to have universal movement. The purpose of the sheave 31 is toassist in the reeving of the necessary cables, etc., for the purpose ofraising the boat in the event of the same becoming disabled whilesubmerged. The structure of the sheave 31 and its manner of operationare disclosed in my co-pending application Ser. No. 592,708, datedNovember 16, 1910, and no claim thereon is made in the resent case.

For stabilizing the signalln apparatus when the same has been releaseand floated the raft is provided with an equilibrator comprising twopairs of weighted arms 33 having pivotal connections 34 with the beams7. The wei hted ends of each pair of said arms are slightly s aced apartand connected by a bolt 35, an on one of said bolts there is pivotallymounted a link 36 adapted to be connected to the other bolt by having ahooked end 37 which engages therewith, when said arms are in functionalposition. In their normal position the arms of the equilibrator aresupported within the deck of the raft through the medium of a chock orblock 38 (see Fig. 1) which seats loosely upon the deck 1, and when inposi-v tion serves as a partition for the coils of the cable 26 andhawser 28.

It is evident that the details of construction and the arrangement ofparts may be varied by those skilled in the art without departing fromthe spirit of my invention and, therefore, I do not wish to be limitedto such features, except as maybe requiredby the claims.

What I claim is 1. The combination with a sub-marine boat, of asignaling apparatus therefor including a mast, a raft supporting saidmast carried by the boat, a conductor cable and a hawser connecting saidapparatus with the boat, a casing in which said cable and hawser areadapted to be coiled, a removable closure for said casing adapted to beheld in position by the raft when said raft is submerged and releasedwhen the raft is floated, and means for releasing said raft to floatwhen the boat is submerged.

2. The combination with a sub-marine boat, of a signaling apparatustherefor including a mast,.a raftsupporting said mast, said raftcomprising air-tight tanks, bands surrounding said tanks provided withclaws, means engaging with said claws for holdin the raft tothe boat; aconductor cable an hawser connecting said raft with the boat, and meanswithin the boat for effecting the release of said claws to permit theraft to float when the boat is submerged.

3. The combination with a sub-marine boat, of a signaling apparatustherefor including a mast, a raft supporting said mast and comprisingbuoyant supports, cradles on said boat supporting said buoyant supports,a conductor cable and a hawser connecting said apparatus with the boat,a casing mounted on the boat intermediate said cradles and adapted tohave coiled therein said cableand hawser; a removable closure for saidcasing adapted to be held in posi tion by the raft when said raft issubmerged and released when the raft is floated; and means for releasingsaid raft to float, when the boat is submerged.
